Generic diagnosis
Flowers subtended by bracts. Bracts fused basally. Flowers pedicellate, actinomorphic, epigynous, with inferior ovary. Sepals 4–5, rounded in shape, each with usually 4–6 longitudinal ribs in the center and two lateral rib-free laminar areas, attached to the receptacle rim with their whole bases, surrounding the petals when immature, with epidermal cells with straight cell walls. Petals 4–5, cuneate, concave, each with usually 5–6 longitudinal ribs in the center and two lateral rib-free laminar areas, with rounded tips, surrounding the gynoecium when immature, with epidermal cells with straight cell walls. Gynoecium in the center, unilocular, fully closed by a cup-form receptacle from the bottom as well as sides and by an integral ovarian roof from the above. Style centrally attached on the top of the ovarian roof, dendroid-formed. One to three seeds inside the ovary, elongated oval, hanged on the ovarian wall by a thin funiculus, with the micropyle-like depression almost opposite the chalaza.
